MILEY CYRUS is caught up once again in a nude photo and drug scandal, and sources say her father Billy Ray is furious!

The “Achy Breaky Heart” singer ripped into his daughter after a breast-baring photo circulated among her friends, and she called herself a “stoner” at her 19th birth­day party.

“Billy Ray read Miley the riot act!” an insider close to the family told The ENQUIRER.

“He told her in no uncertain terms that she could seriously damage her career. But Miley has told her dad that she’s almost 20 years old and an adult now. She’s no longer a Disney princess!”

In the shocking photo, which The ENQUIRER has seen, Miley pulls down her white tank top to reveal her left breast. The picture was apparently snapped in 2008, but it’s just now making the rounds among her friends.

And NOW, shockingly  the internet!

But it's not the first time the former “Hannah Montana” star has been involved in a nude photo scandal.

Last May, she flashed her breasts while shopping with her mother Tish during a tour stop in Chile.

Before that, controversial semi-nude photos of Miley were published in “Vanity Fair” magazine – and hacked cell-phone photos of Miley, then 14, taking a shower in a wet T-shirt were circulated.
